These values were taken when refueling using the trip mileage counter and are already averaged per type of driving condition: - 4WD at 7500ft altitude 18L%KM ~~13 USmpg (this one is less accurate) - heavy rain/snow 12.5L%KM ==19 USmpg - local city traffic 11.3L%KM ==21 USmpg - interstate 80mph 10.23L%KM ==23 USmpg - mixed / commuting 10L%KM ==23.5 USmpg - interstate 70mph 9.46L%KM ==25 USmpg My "global" average mileage is now 22.5 USmpg after 3 years and 52,000 miles. This comes to almost 12,500 USD worth of diesel fuel over here

I've driven the same '02 Liberty Sport 4x4 w/ 3.7L engine (not mine - a family member's) on two long-distance trips. The first was a one-way from North Carolina to Maine in October '04, almost all on multi-lane interestates, typically driving with the CC set at 5-10 over the limit. My average MPG (computed the old-fashioned way) was 22.8. This past July I took a round-trip from Maine to upstate New York, about 2/3 on interstates, but a good chunk on rural state roads and some in town, 5-10 over again whenever possible. Average MPG for that trip was 19.9. It ain't great, but it's better than the miserable mileage my on-its-last-legs '95 Trooper is getting - 16 MPG on mostly highways if I'm lucky! |

Greetings all. Just purchased a 2003 Liberty Sport 4wd with the auto transmission. Here's my question - would anyone recommend any simple fixes or upgrades that get a decent payback with fuel economy. I've seen some refer to K&N air filters, figure the obvious stuff like putting air in tires is always good. Any suggestions on things you've done that worked out good?

Replying to: mmontgomery (Oct 20, 2006 9:19 pm) These things I mentioned are very basic to good mpg. However if the things above have been done, here a few things to bring out better mpg on any vehicle. Go to Synthetic 5-30w oil. Make sure the tire pressure is 33 to 36psi. Use the Cruze control as much as possible. Avoid jack rabbit starts. Don't use the defroster any longer than you have to, this uses the air conditioner to take the moisture out of the air, using fuel like in the summer. Don't let the engine warm up for long periods of time. Run some injector cleaner in your gas tank to glean out injectors and valve body. If spark plugs were changed recently, pull one out and make sure its a Champion, and gaped at the right measurement. Look under the Liberty and make sure the gas line does not have a leak of any kind. You can even make sure the transfer case lubercant has been replaced and is clean and full, the same goes for the axles as well. My experience is when someone is trying to sell a used vehicle they make the inside and outside detailed real nice, but the upkeep items they do fool with. You can't see those items, and that's where money gets spent rather rapidly, but it's more important than making the outside and inside look brand new. If you did everything I said the mpg that you will gain proberly won't be what you are wanting to achieve. In tip top shape expect 15 to 16mpg and on the road 17 to 19mpg Farout
